It's amazing that something so small can take so much time to create! I have been working on this small cosmetic display for my Etsy shop for awhile. I had to get the measurements and the proportions just right, which took some experimenting.
I will show you a picture of this small item, and then explain how I take my pictures.
To take the best pictures, I was given advice from other Etsy shop owners and miniaturists. You can create a "light box" using a small rectangular box. I use a small wooden room box that I purchased second hand last year, but you can make your own using foam core.
To get rid of the shadows in the picture, find two very bright lights (LED lights are best) that are approximately the same in terms of brightness. Then you must set them up so that they are angled towards the object you are photographing.
All of this will make a little more sense after seeing the photograph I took of my light box set up. On your camera, make sure the settings are "best". I have a digital point and shoot camera with an enhanced zoom lens If you can afford to buy a digital camera with a detachable lens then your pictures will look even better!
Good luck with your picture taking. It takes a bit of practise but soon becomes easier.
